Title: Original lighting device
Inventor: KIKUCHI YUTAKA
IPC: G03G15/04
Filed: 1980-01-11
Abstract: PURPOSE: To provide a device of high energy saving effect by changing the positions of a pluraity of light sources according to copying magnifications, or causing part of the light sources to emit light selectively.  
     CONSTITUTION: Discrete light sources l 1 Wl 6  are disposed together with a reflection shade 4 in proximity to an original platen glass 1 in a manner as to irradiate an original 2 in the form of slit, whereby the plane parallel to the original face is scanned. The scanning is accomplished by moving in parallel the original face or the light sources l 1 Wl 6  and the reflection shade 4 in combination along guiding members such as rails. When an area of which the length in a slit lengthwise direction is L 1  is to be copied, the light sources l 1 Wl 6  emit light in the illustrated positions, but this layout is determined by taking the decrease in the quantity of the peripheral light of the lens into consideration. For the distribution of the quantity of light at the unmagnification, the light source luminance distributions and the cos 4  law of the lens are offset and the uniform illuminance distribution is obtained on a photosensitive surface 6 as shown in the figure.

Title: Stray light free fourier spectrophotometer
Inventor: MASUTANI KOJI
IPC: G01J3/45
Filed: 1991-01-14
Abstract: PURPOSE:To prevent the reflected light or scattered light from a sample or an optical element from being returned to an interferometer by arranging a mask on an optical path before or after the reflected light from a fixed mirror and a moving mirror is superimposed by a beam splitter. CONSTITUTION:A mask 11 is arranged at the position of a condensing optical system 5 to cut one half of the beam cross section to the optical axis. The surface of the mask 11 is covered with an absorbent, e.g. black paint, and the mask 11 is inclinatorily arranged from the optical axis direction. The light 10 fed to a sample 6 through one side of the optical path and reflected is cut by the mask 11, and the light passing through one half of the opposite side of the optical path is cut by the mask 11 before it is fed to the sample 6, thus no stray light is generated, and no pseudo signal is mixed. A mask cutting off the optical path on one side of the straight line perpendicular to the optical axis is optimum for the mask 11. A double-diameter convex lens or a concave mirror 5' is used for the condensing optical system 5, the half is cut as required, and the optical axis of an optical system 5' may be shifted to the outside.

Abstract: PURPOSE:To obtain a small-sized magnetic levitation motor system magnetically self-levitated without necessity of a separate magnetic bearing system by incorporating a capacity of a magnetic levitation in a motor itself and generating a driving torque. CONSTITUTION:A motor 1 is a motor to be operated by magnetic levitation of a rotary shaft, and driven by supplying currents from inverters 101, 201. The center of a rotary shaft of a rotor of the motor is controlled at the center of the shaft of a stator core to magnetically levitate the shaft of the rotor, a torque is controlled, and the rotor is rotated at a speed responsive to a speed reference. When the center of the shaft is vertically deviated, a displacement sensor senses it to control an axial component current flowing through a winding thereby to increase or decrease a vertical electromagnetic attraction force, thereby returning the center of the shaft of the rotor toward a center thereby to always hold it at a central position. Accordingly, it can be reduced in size and simplified without necessity of a separate magnetic bearing levitation system.
